'The Law of Development Cooperation can justly be celebrated as the 'state of art' of legal reasoning. Every single page of the book is stimulating and full of insights valuable to both development practitioners and legal scholars alike. On the conceptual level, the construction of a multi-layered legal field of development cooperation from an institutional perspective that focuses on the legal norms of donors seems highly plausible. It presents academics with a rich yet workable area for further research.' Giedre Jokubauskaite, European Journal of International Law
